How does salt act as a flavor enhancer in sweet desserts?
Short answer
A little salt makes desserts taste sweeter and richer mainly by suppressing bitterness. Research published in Nature in 1997 showed that sodium blocks bitter tastes, which lets sweetness and other flavours come forward. That's why caramel, chocolate and cookies often include a pinch of salt.
How a pinch of salt changes a dessert
- 1Salt suppresses bitter tastes
- 2Sweetness is released from suppression
- 3Flavours seem rounder and stronger
- 4Result: tastes sweeter, not saltier
What the science says
In a classic 1997 study, researchers Paul Breslin and Gary Beauchamp found that sodium suppressed bitter tastes. When bitterness was reduced, sweetness was released from suppression and seemed stronger. Salt, in other words, works less by adding saltiness than by taking bitterness away.
Where you notice it
- Chocolate and coffee desserts, which have natural bitterness.
- Caramel, where salt balances the slightly bitter notes of cooked sugar.
- Fruit such as grapefruit or melon, which some people eat with a pinch of salt.
How much?
Usually a pinch to ¼ teaspoon in a batch of cookies or a cake. Salted desserts with visible flakes, like salted caramel, use more for contrast.
